ABSTRACT:
A system and method for establishing, maintaining or enhancing microorganisms utilized to remediate contaminated soil or groundwater which includes of a direct push rod or cylinder equipped with a fluid or gas delivery system. The system also includes computer-based monitoring capabilities which can monitor or control the subsurface events. Microorganisms, nutrient solutions, or gases such as air can be introduced into the subsurface environment of predetermined locations. The delivery device is a long rod or cylinder which is pushed into the ground via applied pressure at the surface. The internals of this device contain tubing or other means to deliver fluid through openings in the rod or cylinder to the surrounding environment. The fluid may be driven into the environment by surface pumps or gas pressure. The delivery rod or cylinder may be withdrawn for reutilization or left in place for continuous service.
